ESCRIPTION
The ICS83905 is a low skew, 1-to-6 LVCMOS / LVTTL
Fanout Buffer and a member of the HiPerClockS™
HiPerClockS™
family of High Performance Clock Solutions from IDT.
The low impedance LVCMOS/LVTTL outputs are de-
signed to drive 50Ω series or parallel terminated
transmission lines. The effective fanout can be increased from 6
to 12 by utilizing the ability of the outputs to drive two series
terminated lines.
F
EATURES
Six LVCMOS / LVTTL outputs
Outputs able to drive 12 series terminated lines
Crystal oscillator interface
Crystal input frequency range: 10MHz to 40MHz
Output skew: 80ps (maximum)
RMS phase jitter @ 25MHz, (100Hz - 1MHz):
0.26ps (typical) (V

The ICS83905 is characterized at full 3.3V, 2.5V, and 1.8V,
mixed 3.3V/2.5V, 3.3V/1.8V and 2.5V/1.8V output operating
supply mode. Guaranteed output and part-to-part skew char-
acteristics along with the 1.8V output capabilities makes the
ICS83905 ideal for high performance, single ended applica-
tions that also require a limited output voltage.
